:51 This invention relates to 1 an adjustable :motor base, and has forone of its-objects 'theiproduction of a simple and-efficientmotorbase-which maybe adjusted to clamptmotors of various: sizes firmlyin position upon the adjustable motor-base.

A further object of' thisinvention is the production o'fassimplean'defficientmea'ns for attaching a motor to the adjustable 'smo'tor'base'by means of a U -bolt:clamp'--whic'h may be swung to selected clampingpositions.

Other objects and advantageso'f this invention will appear throughout"the following specification and claims.

In the drawing:

Figure 1 isa'perspectiveview' of the adjustable motor base;

"taken on .line 4-4 loflFfigure :2, and showing the U-bolt clamp in avertical .position;

Figure is a fragmentary sectional perspective View of themotor-supporting casing.

"By referring to the drawingpit will beseen that In designates asuitable support upon which the adjustable motor base is anchored in anyconventional manner. The adjustable motor base comprises a bottomtray-like member II having upstanding parallel side flanges I2. A pairof longitudinally extending track-Ways I3 are secured to the upper faceof the member I I and are provided with overhanging flanges I4 which arespaced from the flanges I2 and spaced from the upper face of the memberII to provide track channels for receiving the inturned flanges I5 ofthe motor-supporting casing IS.

The casing I6 extends above the member I I and is slidablelongitudinally of the member II. An upstanding bracket I1 is secured toone end of the member I l and a threaded adjusting bolt I8 is adjustablymounted through the bracket H. The bolt I8 carries a bead l9 at itsouter end and a suitable nut 20 which abuts the inner face of thebracket IT, as shown in Figure 2. A depending bracket 2| is carried bythe casing I5 and a suitable nut 22 is fixed to the inner face of thebracket 2|. The adjusting bolt I8 is threaded through the nut 22 so asto adjust and move the casing I6 longitudinally of the member II andtrackways I3 as the bolt I8 is rotated.

The casing I8 is provided with a pair of transversely extendingelongated aligned slots 23 upon the top portion of the casing I6 andnear one end thereof. Anchoring bolts24 extend vertically through theapertures 23 and through the-conventional apertures 25 atoneendof themo'torZB to fit motors of various widths. Only 'thelower portion ofthemotorZS has been shown 'sin'ce'the invention herein described is notlimited "to any particular type of motor. 'The casing I6 *is alsoprovided with longitudinally extending elongated apertures or slots 21which are located "in transverse alignment, one slot *or aperture 2-!being located near each side of the casingI B. The inher edge of eachaperture 'or--'slot' 2l is provided with a plurality of "parallel 'cuts28 and-the material between the cuts 28is bent,-tilted, inclined ordownwardly bent to provide downwardly "inclinedtongues 29 alongthe-inner edge of-each aperture or slot 21.

A U-shaped clamping bolt -30 extends transversely underthe upper face'ofthe casing P6,- as

shown in Figure 4, and the bolt-38 is provided with upstanding ends 3|which extend through *the aperture 21. A clamping plate'32 "is carriedby these upstanding ends'3I and is-a'daptedto-overhang'a portion of themotor 26, as shown "in Figures 2 and 4. Suitable Wing nuts33 are carriedby theends -3I of the U -bolt -39 for 'clampingthe plate 32 firmly'inengagementwith the"motor=-26. It should be noted that the U-bolt 30 maybe set in a vertical position, as shown in Figure 4, and in dotted linesin Figure 2, or it may be swung toward either side of the vertical axisthereof to clamp motors of various sizes in position. The U-bolt 30 isshown swung to a forward clamping position to clamp a relatively shortmotor in place. The transverse portion of the bolt 3|] by fitting behindthe inclined tongues 29, will be firmly anchored against slidingmovement longitudinally of the slots 21 while at the same time clampingthe motor in position, and while the upstanding ends 3| extend at anincline to the vertical axis of the U-bolt. The combination of theU-bolt 30 with the inclined tongues 29 which act as abutments for theU-bolts 30 provides an eificient means for reaching and clamping motorsof various base lengths in position. The inclined tongues 29 providefulcrums against which the U-bolt 30 may be pivoted.

From the foregoing description, it will be seen that a very simple andeflicient means has been provided which may be easily adjusted to firmlyclamp and support motors of various base lengths in position, therebyavoiding the necessity of providing a large number of supports, each ofa different size or length.

It should be understood that certain detail changes may be made in thestructure described, so long as these changes fall within the scope ofthe appended claims.

Having described the invention, what I claim is:

1. An adjustable motor base comprising a casing, a supporting portion,said casing having a plurality of aligned anchoring bolt-receiving slotslocated near one end thereof and extending transversely of said casing,motor-anchoring bolts passing through said slots, pivotedmotor-anchoring means secured to said casing and mounted for forward andrearward swinging motion for adjustable clamping engagement with motorsof various base lengths, and means engaging said pivoted motor-anchoringmeans for clamping the anchoring means in engagement with a motor base.

2. An adjustable motor base comprising 2. casing, a supporting portion,said casing having a plurality of aligned anchoring bolt-receiving slotslocated near one end thereof and extending transversely of said casing,motor-anchoring bolts passing through said slots, a U-shaped clampingbolt secured to said casing and mounted for forward and rearwardswinging motion for adjustable clamping engagement with motors ofvarious base lengths, a clamping member carried by said bolt, andclamping nuts carried by said bolt for clamping said member inengagement with a motor base.

3. An adjustable motor base comprising a casing, a supporting portion,said casing having a plurality of aligned anchoring bolt-receiving slotslocated near one end thereof and extending transversely of said casing,motor-anchoring bolts passing through said slots, a U-shaped clampingbolt secured to said casing and mounted for forward and rearwardswinging motion for adjustable clamping engagement'with motors ofvarious base lengths, a clamping member carried by said bolt, clampingnuts carried by said bolt for clamping said member in engagement with amotor base, said casing having a plurality of laterally spacedlongitudinally extending slots, said U- shaped bolt having a transverseportion extending under the upper face of the casing and a plurality ofupstanding ends extending through said last-mentioned slots, said slotshaving abutments on edges thereof for receiving said transverse portionof said U-bolt to hold the upstanding ends of the U-bolt in an inclinedposition in a manner whereby the clamping member may engage motors ofvarying lengths to anchor the motor in position.

4. An adjustable motor base comprising a casing, a supporting portion,said casing having a plurality of aligned anchoring bolt-receiving slotslocated near one end thereof and extending transversely of said casing,motor-anchoring bolts passing through said slots, a U-shaped clampingbolt secured to said casing and mounted for forward and rearwardswinging motion for adjustable clamping engagement with motors ofVarious base lengths ,a clamping member carried by said bolt, clampingnuts carried by said bolt for clamping said member in engagement with amotor base, said casing having a plurality of laterally spacedlongitudinally extending slots, said L shaped bolt having a transverseportion extending under the upper face of the casing and a plurality ofupstanding ends extending through said last-mentioned slots, said slotshaving transversely slotted inner side edges defining inclined tonguesfor receiving said transverse portion of said U-bolt to hold theupstanding ends of the U-bolt in an inclined position in a mannerWhereby the clamping member may engage motors of varying lengths toanchor the motor in position.
